i need help for a spring wedding i dont know what colors to go on his colors are red and blue and my colors are purple,pink and yellow can someone please help

How about trying for some shades of compromise? Maybe a light red/near dark pink, a blueish-purple shade to pair with it and then perhaps let the yellow go (or maybe try to find a shade that would go with it)? Just throwing out ideas...don't crucify me for it, please!

I agree with la_missourienne let the yellow go and try a light blue or a lighter color that will compliment both his and your color choices
